Hi~!

Device is i.MX 8M mini evk

yocto version is imx-4.14.78-1.0.0_ga

I have been trying ir-receiver solution.

1. I tried to modify the dts file as below

.../tmp/work-shared/imx8mmevk/kernel-source/arch/arm64/boot/dts/freescale/fsl-imx8mm-evk.dts

&iomux {

pinctrl-names = "default";

}

2. Kernel Compile..

$ bitbake -c devshell virtual/kernel

------------------------------

make Image

make modules

make dtbs

------------------------------

$ bitbake -C compile virtual/kernel

3. And Copy&Paste new dtb file in My SD-card

4. but, It doesn't apply.

Unfortunately, I'm not familiar with embedded Linux.

Please suggest me how can I supposed to add GPIO.

Best Regards,
